linux - 如何在 upstart 脚本中使用多个 exec 命令？

Question

这是我尝试运行多个 exec 命令的方法，但我得到的是电子邮件输出，但不是短信。有没有办法运行 both exec 命令？

description "starts a kafka consumer for email and sms "
respawn

start on runlevel [2345]
stop on runlevel [!2345]

env FOUNDATION_HOME=/opt/home/configs
env VIRTUAL_ENV=/opt/home/virtualenvs/analytics


# run as non privileged user
setuid xxx
setgid xxx

console log

chdir /opt/xxx


exec  stdbuf -oL /opt/xxx/virtualenvs/analytics/bin/python -m yukon.pipelinerunnerexternal /opt/xxx/configs/datastream.pheme_sms  > /tmp/sms.out 2>&1

exec  stdbuf -oL /opt/xxx/virtualenvs/analytics/bin/python -m yukon.pipelinerunnerexternal /opt/xxx/configs/datastream.pheme_email > /tmp/email.out  2>&1

post-start script
    PID=`status kafka_upstart | egrep -oi '([0-9]+)$' | head -n1`
    echo $PID > /var/tmp/kafka_upstart.pid
end script

post-stop script
    rm -f /var/tmp/kafka_upstart.pid
end script

您可以尝试将它们与 && 连接起来(假设它们不会无限期地阻塞):

exec  stdbuf -oL /opt/xxx/virtualenvs/analytics/bin/python -m yukon.pipelinerunnerexternal /opt/xxx/configs/datastream.pheme_sms  > /tmp/sms.out 2>&1 && stdbuf -oL /opt/xxx/virtualenvs/analytics/bin/python -m yukon.pipelinerunnerexternal /opt/xxx/configs/datastream.pheme_email > /tmp/email.out  2>&1

或者将命令放在一个单独的脚本中，kafkalaunch.sh，然后运行脚本:

exec kafkalaunch.sh

我认为哪个更优雅。
